What effect does increased physical activity generally have on lipid levels?

Increased physical activity is generally associated with improving HDL levels, often referred to as "good" cholesterol. Regular exercise promotes the metabolism of lipids, leading to a decrease in the levels of triglycerides while simultaneously enhancing the formation and circulation of HDL cholesterol. HDL plays a crucial role in transporting cholesterol away from the arteries and towards the liver, where it can be processed and eliminated from the body. This is significant as higher levels of HDL cholesterol are linked to a reduced risk of cardiovascular diseases.

Engaging in consistent physical activity can also contribute to weight management and improved insulin sensitivity, which further supports healthy lipid profiles. Therefore, the correct answer reflects the beneficial effect of exercise on lipid levels, particularly by increasing HDL cholesterol.
